good A&P & avionics rec's in/between Houston & Austin

Since moving to the Houston area I have had trouble finding a good mechanic
and avionics facility for my 1962 Comanche.

Since I live 60 miles west of d/t Houston anywhere really between Austin and
Houston (and 75 miles North/South of that corridor) would qualify.

I am finding a lot of unreturned phone messages which I find annoying and
impolite (and actually a good tip-off that the place is not worth bothering
with anyhow), along with many shops "swamped" or generally too busy with
bigger jobs.

There is no mechanic on my home field nor have I been impressed with
itinerant mechanics in the area who seem to be unimpressive at least in
terms of basic courtesy returning phone calls etc. Or just plain not
interested.

I need someone reliable, who can do a job --without-- 3 months advance
notice, and reasonably good to work with as a customer. It doesn't seem like
it should be that difficult, but it has been proving so for me.

I moved down from Oklahoma where this was never a problem but commuting back
up there to a known mechanic is not really an option. I think the main issue
is not having a local mechanic on the field as call cold to other places you
are always considered a one-off bit of business, at best until proven
otherwise.

Also is there any Web site devoted to sharing "good A&P" tips? I can't find
one if so but it is worth asking. AirNav.com have a few but it takes a lot
of time to wade through to find them.

I also need someone to look at my autopilot so a good avionics place is also
sought.

Many thanks, in advance
